HELP! Leaking Water Line Behind Toilet

Pekoe1111

Hi - I have a 2014 320S and as I was winterizing it last Fall, I heard a water line gushing water behind the toilet, and water coming out from around the toilet base.  I did my best to drain the system and blow out the system.  

With Spring approaching, I’m trying to figure out how I access the water lines in the wall.  Any thoughts?  I don’t have access to the camper right now as it is still in my friend's barn.

Thanks!

@Pekoe1111, I am not sure which toilet you have (Thetford?), but unless you heard the water sound coming from the wall behind the toilet, you may have a leak due to a broken water module/valve at the base of the toilet.  You will need to remove the toilet to access and replace the part.  Take a look at the below threads, which discuss the problem.  However, if the issue is in fact behind the wall, there are discussions on the forum about accessing that area (e.g., see below.)  Maybe another forum member will chime in with their experience accessing that area (not always easy, unfortunately.)
